Full resume


I enjoy coding. I’m focusing on RTC technology now, and I love open source, agile development, and new technologies which I’m definitely willing to try out. I am on my way to become an expert.


I’m Piasy (Jianlin Xu). I receive my Bachelor degree on Computer Science in Tsinghua University at 2015. Now I’m leading the client SDK team at Powerinfo. I appreciate technology, and enjoy dealing real-life challenge with technology. Now I’m focusing on RTC technology, but my sight will never be limited in it. I think solving valuable problems with team members, efficiently and reliably, is the most important thing when building a product. To achieve this, critical thinking, ability to learn new things, and collaborating with others are key points.
